摘要：
A new design of a laboratory installation for determining the strength Pm, plasticity Pl, and contraction DV of solid paraffin-containing petroleum products with automatic recording of measurement results is described. A comparative analysis is made of Pm, Pl, and DV of solid crude oil paraffins, ceresines, and waxes at 25 °C. The mechanisms of formation of disperse structures of commercial paraffin-containing petroleum products and dominant role of n-alkanes in their composition as strength carriers are ascertained. Strain-hardening of the disperse structure of commercial ceresine and wax specimens containing 40-60 % hydrocarbons that do not form a complex with carbamide is observed for the first time.
